12018 Chinese Pediatric Cardiology Society(CPCS) guideline for diagnosis and treatment of syncope in children and adolescents显示文摘Syncope belongs to the transient loss of consciousness(TLOC), characterized by a rapid onset, short duration, and spontaneous complete recovery. It is common in children and adolescents, accounting for 1% to 2% of emergency department visits.Recurrent syncope can seriously affect children's physical and mental health, learning ability and quality of life and sometimes cardiac syncope even poses a risk of sudden death. The present guideline for the diagnosis and treatment of syncope in children and adolescents was developed for guiding a better clinical management of pediatric syncope. Based on the globally recent development and the evidence-based data in China, 2018 Chinese Pediatric Cardiology Society(CPCS) guideline for diagnosis and treatment of syncope in children and adolescents was jointly prepared by the Pediatric Cardiology Society, Chinese Pediatric Society, Chinese Medical Association(CMA)/Committee on Pediatric Syncope, Pediatricians Branch, Chinese Medical Doctor Association(CMDA)/Committee on Pediatric Cardiology, Chinese College of Cardiovascular Physicians, Chinese Medical Doctor Association(CMDA)/Pediatric Cardiology Society, Beijing Pediatric Society, Beijing Medical Association(BMA). The present guideline includes the underlying diseases of syncope in children and adolescents, the diagnostic procedures, methodology and clinical significance of standing test and headup tilt test, the clinical diagnosis vasovagal syncope, postural orthostatic tachycardia syndrome, orthostatic hypotension and orthostatic hypertension, and the treatment of syncope as well as follow-up.Cheng Wang Yaqi Li Ying Liao Hong Tian Min Huang Xiangyu Dong Lin Shi Jinghui Sun Hongfang Jin Junbao Du Jindou An Jie Chen Mingwu Chen Qi Chen Sun Chen Yonghong Chen Zhi Chen Adolphus Kai-tung Chau Junbao Du Zhongdong Du Junkai Duan Hongyu Duan Xiangyu Dong Lin Feng Lijun Fu Fangqi Gong Yonghao Gui Ling Han Zhenhui Han Bing He Zhixu He Xiufen Hu Yimin Hua Guoying Huang Min Huang Ping Huang Yujuan Huang Hongfang Jin Mei Jin Bo Li Fen Li Tao Li Xiaohui Li Xiaoyan Liu Yan Li Haitao Lv Tiewei Lv Zipu Li Luyi Ma Silin Pan Yusheng Pang Hua Peng Yuming Qin Jie Shen Lin Shi Kun Sun Jinghui Sun Hong Tian Jie Tian Cheng Wang Hong Wang Lei Wang Jinju Wang Wendi Wang Yuli Wang Rongzhou Wu Tianhe Xia Yanyan Xiao Chunhong Xie Yanlin Xing Zhenyu Xiong Baoyuan Xu Yi Xu Hui Yan Shiwei Yang Qijian Yi Xia Yu Xianyi Yu Yue Yuan Hongyan Zhang Huili Zhang Li Zhang Qingyou Zhang Xi Zhang Yanmin Zhang Zhiwei Zhang Cuifen Zhao Bin Zhou Hua Zhu 2018Science Bulletin2018,63,23:54

4Rapid isolation and immune profiling of SARS-CoV-2 specific memory B cell in convalescent COVID-19 patients via LIBRA-seq显示文摘B cell response plays a critical role against SARS-CoV-2 infection.However,little is known about the diversity and frequency of the paired SARS-CoV-2 antigen-specific BCR repertoire after SARS-CoV-2 infection.Here,we performed single-cell RNA sequencing and VDJ sequencing using the memory and plasma B cells isolated from five convalescent COVID-19 patients,and analyzed the spectrum and transcriptional heterogeneity of antibody immune responses.Via linking BCR to antigen specificity through sequencing(LIBRA-seq),we identified a distinct activated memory B cell subgroup(CD11c^(high) CD95^(high))had a higher proportion of SARS-CoV-2 antigen-labeled cells compared with memory B cells.Our results revealed the diversity of paired BCR repertoire and the non-stochastic pairing of SARS-CoV-2 antigen-specific immunoglobulin heavy and light chains after SARS-CoV-2 infection.The public antibody clonotypes were shared by distinct convalescent individuals.Moreover,several antibodies isolated by LIBRA-seq showed high binding affinity against SARS-CoV-2 receptor-binding domain(RBD)or nucleoprotein(NP)via ELISA assay.Two RBD-reactive antibodies C14646P3S and C2767P3S isolated by LIBRA-seq exhibited high neutralizing activities against both pseudotyped and authentic SARS-CoV-2 viruses in vitro.Our study provides fundamental insights into B cell response following SARS-CoV-2 infection at the single-cell level.Bing He Shuning Liu Yuanyuan Wang Mengxin Xu Wei Cai Jia Liu Wendi Bai Shupei Ye Yong Ma Hengrui Hu Huicui Meng Tao Sun Yanling Li Huanle Luo Mang Shi Xiangjun Du Wenjing Zhao Shoudeng Chen Jingyi Yang Haipeng Zhu Yusheng Jie Yuedong Yang Deyin Guo Qiao Wang Yuwen Liu Huimin Yan Manli Wang Yao-Qing Chen 2021Signal Transduction and Targeted Therapy2021,6,6:2

7IPNA临床实践建议:儿童激素敏感型肾病综合征的诊断和治疗显示文摘特发性肾病综合征是最常见的儿童肾小球疾病,其特征是大量蛋白尿、低蛋白血症和(或)伴有水肿,全球每年儿童患病率为(1.15~16.90)每10万例。约有85%~90%的患者在接受糖皮质激素治疗的4~6周内可达到蛋白尿完全缓解,表现为激素敏感型肾病综合征(SSNS)。约70%~80%的SSNS患者在随访期间至少复发1次,其中多达50%的患者出现频繁复发或依赖糖皮质激素以维持蛋白尿缓解。为延长复发间隔时间,激素治疗的用药剂量和用药时长始终是热点问题之一,且患者出现激素相关并发症的概率较高。临床已应用多种激素助减药物(免疫抑制药物),但在疾病治疗过程中这些药物的选择和用药时机存在明显差异。因此,需要国际循证临床实践建议(CPRs)来指导临床实践、减少实践差异。国际儿科肾脏病学会(IPNA)召集专家小组通过对12个临床相关PICO(研究对象、干预措施、对照、结果/结局)问题进行系统的文献回顾,制定了关于儿童SSNS诊断和治疗的建议和分级。对治疗转归提出了新的定义,有助于指导治疗改变,并为重要的研究问题提供了参考。Agnes Trautmann Olivia Boyer Elisabeth Hodson Arvind Bagga Debbie S.Gipson Susan Samuel Jack Wetzels Khalid Alhas an Sushmita Banerjee Rajendra Bhimma Melvin Bonilla-Felix Francisco Cano Martin Christian Deirdre Hahn Hee Gyung Kang Koichi Nakanishi Hesham Safouh Howard Trachtman Hong Xu Wendy Cook Marina Vivarelli Dieter Hafner on behalf of the International Pediatric Nephrology Association 韩思雨(翻译) 季丽娜(翻译) 2023中国合理用药探索2023,20,2:1

13Therapeutic effect of Qinghuayin(清化饮)against chronic atrophic gastritis through the inhibition of toll or interleukin-1 receptor domain-containing adaptor inducing interferon-β signaling pathway显示文摘OBJECTIVE:To examine the efficacy of Qinghuayin(清化饮,QHY)in rat chronic atrophic gastritis(CAG)models and explored the molecular mechanism of QHY in treating CAG.METHODS:In total,65 Wistar rats were randomly divided into the control(n=10)and CAG groups(n=55).CAG model rats were further divided into five groups:model(n=10),vitacoenzyme(n=10),low-dose QHY(n=10),medium-dose QHY(n=10),and high-dose QHY groups(n=10).We analyzed histopathological changes using hematoxylin and eosin staining and measured interleukin(IL)-6 and IL-8 levels in serum using enzyme-linked immunosorbent assay(ELISA)(Boster Bio,Pleasanton,USA).In addition,gastrin(GAS),pepsinogen I(PGI),and PGII expressions were evaluated using ELISA.The protein and m RNA expression of toll-like receptor 4(TLR4)and toll or interleukin-1 receptor domaincontaining adaptor inducing interferon-β(TRIF)was detected by Western blotting and quantitative reverse transcription-polymerase chain reaction,respectively.RESULTS:Our results revealed that histopathological changes in CAG model rates could be restored by low-,medium-,and high-dose QHY.The changes in GAS and PGI/II expression demonstrated that QHY improved CAG.Serum IL-6 and IL-levels were decreased by QHY administration.TLR4 and TRIF were upregulated at the m RNA and protein levels in the model group but downregulated by QHY administration.CONCLUSION:We concluded that QHY could effectively improve the histopathological changes of the gastric mucosa induced by CAG in rats.The therapeutic mechanism of QHY may be related to inhibition of the inflammatory factors IL-6 and IL-8 and suppression of TLR4/TRIF m RNA and protein expression.HE Youcheng YAO Xiaoling LI Sihan ZHOU Hongjian XU Ruoying ZHENG Rong XIAO Wendi SU Ning LIN Ping HUANG Minghan 2022Journal of Traditional Chinese Medicine2022,42,2:1

15Proteome profiling of spinal cord and dorsal root ganglia in rats with trinitrobenzene sulfonic acid-induced colitis显示文摘AIM: To investigate proteomic changes in spinal cord and dorsal root ganglia (DRG) of rats with trinitrobenzene sulfonic acid (TNBS)-induced colitis. METHODS: The colonic myeloperoxidase (MPO) activity and tumor necrosis factor-(TNF- ) level were determined. A two-dimensional electrophoresis (2-DE)-based proteomic technique was used to profile the global protein expression changes in the DRG and spinal cord of the rats with acute colitis induced by intracolonic injection of TNBS. RESULTS: TNBS group showed significantly elevated colonic MPO activity and increased TNF-level. The proteins derived from lumbosacral enlargement of the spinal cord and DRG were resolved by 2-DE; and 26 and 19 proteins that displayed significantly different expression levels in the DRG and spinal cord were identified respectively. Altered proteins were found to be involved in a number of biological functions, such as inflammation/immunity, cell signaling, redox regulation, sulfate transport and cellular metabolism. The over-expression of the protein similar to potassium channel tetramerisation domain containing protein 12 (Kctd 12) and low expression of proteasome subunit type-1 (psma) were validated by Western blotting analysis. CONCLUSION: TNBS-induced colitis has a profound impact on protein profiling in the nervous system. This result helps understand the neurological pathogenesis of inflammatory bowel disease.Xiao-Jun Zhang Feung Ping Leung Wendy WL Hsiao Shun Tan Shao Li Hong-Xi Xu Joseph JY Sung Zhao-Xiang Bian 2012World Journal of Gastroenterology2012,18,23:0
16Adaptive evolution to the natural and anthropogenic environment in a global invasive crop pest,the cotton bollworm显示文摘The cotton bollworm,Helicoverpa armigera,is set to become the most economically devastating crop pest in the world,threatening food security and biosafety as its range expands across the globe.Key to understanding the eco-evolutionary dynamics of H.armigera,and thus its management,is an understanding of population connectivity and the adaptations that allow the pest to establish in unique environments.We assembled a chromosome-scale reference genome and re-sequenced 503 individuals spanning the species range to delineate global patterns of connectivity,uncovering a previously cryptic population structure.Minghui Jin Henry L.North Yan Peng Hangwei Liu Bo Liu Ruiqing Pan Yan Zhou Weigang Zheng Kaiyu Liu Bo Yang Lei Zhang Qi Xu Samia Elfekih Wendy A.Valencia-Montoya Tom Walsh Peng Cui Yongfeng Zhou Kenneth Wilson Chris Jiggins Kongming Wu Yutao Xiao 2023The Innovation2023,4,4:0
17Crystallography of low Z material at ultrahigh pressure:Case study on solid hydrogen显示文摘Diamond anvil cell techniques have been improved to allow access to the multimegabar ultrahigh-pressure region for exploring novel phenomena in condensedmatter.However,the onlyway to determine crystal structures of materials above 100 GPa,namely,X-ray diffraction(XRD),especially for lowZ materials,remains nontrivial in the ultrahigh-pressure region,even with the availability of brilliant synchrotron X-ray sources.In thiswork,we performa systematic study,choosing hydrogen(the lowest X-ray scatterer)as the subject,to understand how to better perform XRD measurements of low Z materials at multimegabar pressures.The techniques that we have developed have been proved to be effective in measuring the crystal structure of solid hydrogen up to 254GPa at room temperature[C.Ji et al.,Nature 573,558–562(2019)].Wepresent our discoveries and experienceswith regard to several aspects of thiswork,namely,diamond anvil selection,sample configuration for ultrahigh-pressure XRDstudies,XRDdiagnostics for low Z materials,and related issues in data interpretation and pressure calibration.Webelieve that these methods can be readily extended to other low Z materials and can pave the way for studying the crystal structure of hydrogen at higher pressures,eventually testing structural models of metallic hydrogen.Cheng Ji Bing Li Wenjun Liu Jesse S.Smith Alexander Bjoorling Arnab Majumdar Wei Luo Rajeev Ahuja Jinfu Shu Junyue Wang Stanislav Sinogeikin Yue Meng Vitali B.Prakapenka Eran Greenberg Ruqing Xu Xianrong Huang Yang Ding Alexander Soldatov Wenge Yang Guoyin Shen Wendy L.Mao Ho-Kwang Mao 2020Matter and Radiation at Extremes2020,5,3:0
18Expression profiling of the BpIAA gene family and the determination of IAA levels in Betula platyphylla tetraploids显示文摘Betula platyphylla Sukaczev tetraploids have significantly larger leaf, fruit and stoma (gigantic phenotype) than diploids of the same species;however, the mechanism underlying this difference remains unclear. Tetraploid B. platyphylla transcriptome data have indicated that the expression of genes related to indole-3-acetic acid (IAA) biosynthesis and signal transduction was altered after genome duplication. IAA exerts pleiotropic effects on growth and development by inducing the expression of Aux/IAA. We identified 20 Aux/IAA genes (BpIAA1– BpIAA20) in B. platyphylla distributed across 10 chromosomes. Multiple alignment and motif analyses revealed that nine BpIAA proteins shared all four conserved domains. Phylogenetic analysis indicated that Aux/IAA families were divided into four subfamilies and that there were two pairs of BpIAA sister genes. The BpIAAs were differentially expressed in diploids and tetraploids. Moreover, the expression levels of the nine BpIAA genes were specifically up-regulated in tetraploids from June to September compared with May (except August 5th) in tetraploids, while they were down-regulated in diploids. IAA levels were more than twofold higher in tetraploids than diploids during the vegetative season. These results indicate that genome duplication of B. platyphylla caused the up-regulated of genes involved in IAA synthesis, and the increased concentration of IAA may induce the constitutive expression of 20 BpIAA genes. Therefore, the significant changes in the expression patterns of the BpIAAs contributed to the gigantic phenotype of tetraploids to some extent. Our research sheds light on the phenotypic variations observed in B. platyphylla tetraploids.Wendi Xu Su Chen Jing Jiang Guifeng Liu 2019Journal of Forestry Research2019,30,3:0
19Influence of functional groups on the self-assembly of liquid crystals显示文摘Functional groups in the molecule play an important role in the molecular o rganization process.To reveal the influence of functional groups on the self-assembly at interface,herein,the self-assembly structures of three liquid crystal molecules,which only differ in the functional groups,are explicitly characterized by using scanning tunneling microscopy(STM).The high-resolution STM images demonstrate the difference between the supramolecular assembly structures of three liquid crystal molecules,which attribute to the hydrogen bonding interaction andπ-πstacking interaction between different functional groups.The density functional theory(DFT)results also confirm the influence of these functional groups on the self-assemblies.The effort on the self-assembly of liquid crystal molecules at interface could enhance the understanding of the supramolecular assembly mechanism and benefit the further application of liquid crystals.Shanchao Tan Jiayu Tao Wendi Luo Hao Jiang Yuhong Liu Haijun Xu Qjngdao Zeng Hongyu Shi 2021Chinese Chemical Letters2021,32,3:0
20Mesoporous poly(ionic liquid)s with dual active sites for highly efficient CO_(2)conversion显示文摘Atmospheric CO_(2)concentrations are soaring due to the continued use of fossil fuels in energy production,an anthropogenic activity that is playing a leading role in global warming.Thus,research aimed at the capture and conversion of CO_(2)into value-added products,such as cyclic carbonates,is booming.While CO_(2)is an abundant,cheap,non-toxic,and readily accessible Cl feedstock,its thermodynamic stability necessitates the development of highly efficient catalysts that are able to promote chemical reactions under mild conditions.In this work,a novel mesoporous poly(ionic liquid)with dual active sites was synthesized through a facile method that involves co-polymerization,post-synthetic metalation,and supercritical CO_(2)drying.Due to a high density of nucleophilic and electrophilic sites,the as-prepared poly(ionic liquid),denoted as P2D-4BrBQA-Zn,offers excellent performance in a CO_(2)cycloaddition reaction using epichlorohydrin as the substrate(98.9%conversion and 96.9%selectivity).Moreover the reaction is carried out under mild,solvent-free,and additive-free conditions.Notably,P2D-4BrBQA-Zn also efficiently promotes the conversion of various other epoxide substrates into cyclic carbonates.Overall,the catalyst is found to have excellent substrate compatibility,stability,and recyclability.Yawen Fu Yanan Xu Zepeng Zeng Abdul-Rauf Ibrahim Jin Yang Shuliang Yang Yaqiang Xie Yanzhen Hong Yuzhong Su Hongtao Wang Yanliang Wang Li Peng Jun Li Wendy L.Queen 2023Green Energy & Environment2023,8,2:0
